2 Sheets-Sheet 2 Filed Dec. 27, l946 Mario Patented June 21, 1949 UNITED STTES OFFICE This invention relates to a novel construction of lamp shades for use with a conventional type of light source and which is so constructed that the light rays will be reflected therethrough so as to produce a continuous illumination from the light source around the exterior of the shade and by means of which the light rays, reflected outwardly from the shade may be directed as desired.

More particularly, it is an object of the invention to provide a lamp shade of extremely simple construction which may be readily placed on a conventional lamp stand or pedestal and accordingly which may be readily substituted for conventional lamp shades.

Another object of the invention is to provide a shade for a light source formed of a plurality of overlying reflecting surfaces and which may be suitably colored for coloring the light rays reflected therefrom.

Still a further object of the invention is to provide a construction of lamp shade which may be used in conjunction with fixedly mounted electrical fixtures for reflecting light rays either outwardly, or upwardly, or downwardly.

Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawings, illustrating a preferred embodiment of the invention, and wherein:

Figure 1 is a top plan View, partly in horizontal section, illustrating a preferred embodiment of the invention in an applied position;

Figure 2 is an enlarged vertical sectional view taken substantially along a plane as indicated by the line 2--2 of Figure 1;

Figure 3 is an enlarged fragmentary horizontal sectional view of a portion of the shade;

Figure 4 is a vertical sectional view taken substantially along a plane as indicated by the line 4-4 of Figure 3, and

Figure 5 is an enlarged horizontal sectional view of a portion of the shade and showing one of the connecting and spacing elements thereof.

Referring more specifically to the drawings, a preferred embodiment of the lamp shade, comprising the invention and designated generally 6, is illustrated substantially in its entirety in Figure 1. The lamp shade 6 comprises a plurality of outer reflector elements, each designated generally l and a plurality of inner reflector elements, each designated generally 8. The reflector elements 1 and 8 may be formed of any suitable reflecting material, such as aluminum which may be tinted or colored in any desired shade so that the light rays reflected outwardly from the annular shade 6 will be thereby colored. Each of the reflector elements I and 8 are substantially V- shaped in cross section, as clearly illustrated in Figure 1 and said elements 1 and 8 are connected in slightly overlapping relationship by fasteners, designated generally 9, each including an intermediate spacing portion iii, restricted shank portions H and enlarged heads 52. The shank portions ll extend through complementary openings It in adjacently disposed. sides of the reflector members 7 and 6, it being readily apparent that each of the fasteners 9 is connected to a reflector member 7 and a reflector member 8. The fastenings 9 are disposed adjacent the top and bottom edges of the shade 6 or adjacent the ends of the reflector members, each of the reflector members being engaged by four of the fasteners 9 and connected thereby to adjacent sides of two other reflector members. As clearly illustrated in Figure 1, each of the reflector members 1 is connected to adjacent portions of two adj acently disposed reflector members 8, and conversely, each reflector member 8 is similarly connected to two reflector members i.

The reflector members i and 8 when thus connected are arranged to form an endless, preferably annular shade and in the embodiment of the invention as illustrated, said shade 6 converges upwardly so that it is greater in diameter at its lower edge than at its upper edge.

The shade 6 is adapted to be mounted around a light source hi, such as a conventional light bulb, as illustrated, but obviously may be utilized in conjunction with any other desired type of lighting source. The light source I4 is shown mounted in a socket [5 on the upper end of a stand or pedestal it having a collar or enlargement I! for supporting a ring or annulus l8 of a shade supporting frame, designated generally l9, and which also includes a plurality of rods 20 which are anchored at their inner ends to the ring l8 and which radiate therefrom and are provided at their outer ends with downwardly bowed portions 2|, disposed to receive the intermediate portions of the lower ends of certain of the reflector members i for detachably supporting the shade 6 concentrically around the light source l4. Obviously, various other types of lamp shade supports or mountings could be utilized as the shade 6 is adapted to be mounted in a manner conventional to lamp shades and the support I9 is intended merely to illustrate one conventional form of lamp shade support.

Both sides of the inner reflector members 8 faces 25 of the inner reflector members 8 from,

which the light rays will be reflected outwardly and upwardly, due to the upwardly and inwards ly inclined disposition of each of the reflecting members 1 and 8. It will thus be readily apparent that the light rays will be reflected outward! ly in substantially all directions from the outer side of the shade 6 so that the maximum amount of illumination will be provided and if the light source and lamp shade are disposed reasonably close to a ceiling of an enclosure, indirect lighting will thus be obtained and which will be very uniform and in addition to the direct light rays emitted from the open bottom of the shade and the indirect lighting afforded by the light rays emitted directly from the open top of the shade.

Obviously, the shade 6 could be mounted on a fixedly disposed electrical fixture, including a ceiling fixture, and if desired; the shade could be inverted so that the light rays therefrom would be reflected outwardly and downwardly or said shade could'be constructed so that the members I and 8 would be disposed perpendicularly to the light source for reflecting the light rays directly outwardly from the shade.

Various other modifications and changes are likewise contemplated and may obviously be resortedto, without departing from the spirit and scope of the invention as hereinafter defined by the appended claims.

I claim as my invention;

1. In a lamp shade, a plurality of reflector members each of substantially V-shaped cross section, a plurality of connecting elements for connecting said reflecting elements or members in spaced overlapping relationship whereby said reflectin members will bedisposed to face alternately in opposite directions, and the adjacent edges of adjacently disposed and correspondingly facing reflecting members being spaced from one another whereby light rays directed toward one side of the shade will enter through certain of said spaces and be reflected a plurality oftimes from a plurality of surfaces of said reflecting members and projected outwardly through spaces of other of the reflecting members.

2. A lamp shade as in claim 1, said shade being annular and being adapted to be disposed substantially concentrically around a light source.

3. A lamp shade as in claim 1, said shade being annular and being adapted to be disposed substantially concentrically around .a light source, and said shade bein of a greater diameter at one end than at the opposite end thereof.

4. A lamp shade comprising a plurality of reflecting elements each composed solely of two angularly disposed surfaces both sides of at least certain of which reflecting elements form reflecting surfaces, and connecting and spacing means for connecting said elements in partially overlapping, spaced relationship and with alternate elements thereof facing in the same direction and with reflecting elements disposed therebetween facing in the opposite direction, whereby light rays will be reflected from a plurality of the surfaces of the elements and through a plurality of the spaces therebetween in passing from one side of the shade to the opposite side thereof.

5. A lamp shade comprising a plurality of refleeting members disposed in spaced apart, slightlyoverlapping relationship and each having only two angularly disposed sides, one or both faces of each of said sides forming reflecting surfaces,

and said reflecting members being constructed and arranged whereby alternate members will be facing in the same direction and the members disposed therebetween facing in the opposite di- 1 rection for reflecting light rays from one side of the lamp shade outwardly of the other side thereof.
